IMPORTANT NOTICE AND DISCLAIMER On 25 February 2013 management and administration of the WaterMark Certification Scheme transferred to the Australian Building Codes Board (ABCB). From this date all new technical specifications will be named WaterMark Technical Specifications (WMTS). Within two years all existing ATS will be renamed WMTS. During this initial period both terms may be used and accepted. All new and recertified Certificates of Conformity will reference WMTS. Certificates of Conformity that currently reference ATS will be re-issued referencing the equivalent WMTS during this initial period. The WaterMark Schedule of Specifications lists all current WMTS and, where appropriate, the former ATS name.
This Technical Specification supersedes Standards Australia ATS 5200.103 – 2004.
The rebranding of this Technical Specification has included additional information about the transition as well as changes to specific details including replacing references to Standards Australia and the National Plumbing Regulators Forum (NPRF) with the ABCB, changing the term Australian Technical Specification (ATS) to WaterMark Technical Specification (WMTS), replacing references to technical committees WS-014 and WS-031 with the WaterMark Technical Advisory Committee (WMTAC).
While the ABCB, the participating Governments and other groups or individuals who have endorsed or been involved in the development of the WMTS, have made every effort to ensure the information contained in this document is accurate and up to date, such information does in no way constitute the provision of professional advice.

PREFACE WaterMark Technical Specification WMTS-103: 2016 Technical Specification for plumbing and drainage products, Water treatment systems (other than those specified in AS/NZS 3497) was originally prepared by the Joint Standards Australia/Standards New Zealand Committee WS-031, Technical Procedures for Plumbing and Drainage Products Certification.
The objective of this Technical Specification is to enable product certification in accordance with the requirements of the Plumbing Code of Australia (PCA).
The word ‘VOID’ set against a clause indicates that the clause is not used in this Technical Specification. The inclusion of this word allows a common use clause numbering system for the WaterMark Technical Specifications.
The term ‘normative’ has been used in this Technical Specification to define the application of the appendices to which they apply. A ‘normative’ appendix is an integral part of a Technical Specification.
The test protocol and information in this Technical Specification was arranged by committee members to meet the authorization requirements given in the PCA.
The WaterMark Schedule of Specifications and List of Exempt Products are dynamic lists and change on a regular basis. Based on this function, these lists have been removed from the WaterMark Certification Scheme document known as Technical Specification for Plumbing and Drainage Products and are now located on the ABCB website (www.abcb.gov.au). These lists will be version controlled with appropriate historic references.

The water systems componentry covered by this Technical Specification includes the following:
(a) Storage tanks, with a maximum operating pressure of 860 kPa at 48°C.
(b) Deionizing tank with a maximum operating pressure of 860 kPa at 48°C.
(c) Strainers.
(d) Water sanitizers (including UV).
(e) Water treatment units, upstream of appliances for performance verification in accordance with AS/NZS 4348.
(f) UV for non-drinking water purposes, i.e., bathing.
NOTE: This list is not exhaustive.
APPLICATION This Technical Specification will be referenced on the WaterMark Certification Scheme Schedule of Specifications.
Appendix A sets out the means by which compliance with this Technical Specification shall be demonstrated by a manufacturer for the purpose of product certification.

Appendix A MEANS FOR DEMONSTRATING COMPLIANCE WITH THIS TECHNICAL SPECIFICATION
(Normative)
A.1 SCOPE
This Appendix sets out the means by which compliance with this Technical Specification is to be demonstrated by a manufacturer under the WaterMark Certification Scheme.
A.2 RELEVANCE
The long-term performance of plumbing systems is critical to the durability of building infrastructure, protection of public health and safety, and protection of the environment.
A.3 PRODUCT CERTIFICATION
The purpose of product certification is to provide independent assurance of the claim by the manufacturer that products comply with this Technical Specification.
The certification scheme serves to indicate that the products consistently conform to the requirements of this Technical Specification.
The sampling and testing plan, as detailed in Paragraph A5 and Table A1, shall be used by the WaterMark Conformity Assessment Body. Where a batch release testing program is required it shall be carried out by the manufacturer as detailed in Paragraph A5 and Table A2.
A.4 DEFINITIONS
A.4.1 Batch release test
A test performed by the manufacturer on a batch of components, which has to be satisfactorily completed before the batch can be released.
A.4.2 Production batch
Clearly identifiable collection of units, manufactured consecutively or continuously under the same conditions, using material or compound to the same specification.
A.4.3 Sample
One or more units of product drawn from a batch, selected at random without regard to quality.
NOTE: The number of units of product in the sample is the sample size.
WaterMark Technical Specification: WMTS-103:2016
Page 10 Australian Building Codes Board
A.4.4 Sampling plan
A specific plan that indicates the number of units of components or assemblies to be inspected.
A.4.5 Type test batch
Schedule of units of the same type, identical dimensional characteristics, all the same nominal diameter and wall thickness, from the same compound. The batch is defined by the manufacturer.
A.4.6 Type testing (TT)
Testing performed to demonstrate that the material, component, joint or assembly is capable of conforming to the requirements given in the Technical Specification.
A.5 TESTING
A.5.1 Type testing
Table A1 sets out the requirements for type testing and frequency of re-verification.
A.5.2 Batch release testing
Table A2 sets out the minimum sampling and testing frequency plan for a manufacturer to demonstrate compliance of product(s) to this Technical Specification on an ongoing basis. However, where the manufacturer can demonstrate adequate process control to the WaterMark Conformity Assessment Body, the frequency of the sampling and testing nominated by the manufacturer’s quality plan and/or documented procedures shall take precedence for the purposes of WaterMark product certification.
A.5.3 Retesting
In the event of a test failure, the products within the batch shall be tested at an appropriate acceptable quality level (AQL) and only those batches found to comply may be claimed and/or marked as complying with this Technical Specification.
